"Create the best one-serving tuna fried rice recipe using imperial units. Keep it simple and balanced: use chilled cooked white rice, canned tuna in water if possible, chopped garlic, sesame oil, egg, and soy sauce as the main seasoning. Avoid teriyaki and oyster sauce unless truly needed. Make it flavorful, not too salty, and easy for a beginner. Include ingredient amounts and clear steps."
